1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo examine the effect of prophylactic theophylline for the prevention of severe renal dysfunction in post-asphyxiated term and post-term infants. STUDY

designSystematic review and meta-analysis of randomized controlled trials (RCTs) comparing prophylactic theophylline vs placebo in term infants following perinatal asphyxia.

resultFour RCTs involving 197 infants were included in the meta-analysis. Compared with placebo, prophylactic theophylline was associated with a significant reduction in the incidence of severe renal dysfunction (pooled relative risk) using fixed-effects model was 0.38 (95% confidence interval, 0.25 to 0.57; P<0.001).

conclusionThe meta-analysis provides evidence that prophylactic theophylline significantly reduce the incidence of severe renal dysfunction. However, because of the lack of information on the long-term renal and neurodevelopmental outcome and measured theophylline levels with relation to adverse effects observed, prudence with the clinical use of prophylactic theophylline is required. Additionally, the included trials were prior to the era of therapeutic hypothermia and thus inference of renal benefit in an infant undergoing hypothermia therapy cannot be made.
